Re: Swap Utilization
swap is reserved when a process is launched, based on memory requirements. For many daemon processes this never changes.
HP-UX factoid:
Memory is calculated by physical memory plus swap.
Therefore 74% of your total which is approximately 32 GB is being "used"
This may or may not be a problem. I would take a look at vmstat output to see if there is paging.
reserving swap is not necessarily a problem. Once processes are being paged to and from swap, in and out of active memory, then this may be a problem.
If there is a problem, the normal responses are:
1) Reduce memory use.
2) Increase physical memory.
If you wish to pursue details, post vmstat output and the output of the command model.

Re: Swap Utilization
>I need to know what this TOTAL states. Is this is the actual swap utilization %?
Yes, that's what Total means. 24.5 Gb is 74% of 33.2 Gb.
Note this is how much swap that's reserved, not how much has been swapped yet.
(Notice the large "reserve" but small used under "dev".
